I have a 210 gal tank. I know the dat will get bigger. Right now "Sid" is only about 2 inches and was only about 1 inch when I got him. Currently have Roseline Sharks, Clown Loaches, Ropefish, Boesemani Rainbows, Gold Nugget Pleco, Peppermint Pleco. Are any of these in danger in the future, and if so (and I suspect some will be), at what size of the dat should I remove some/all. I would rather sell some of my current stock than start loosing them, especially my Roselines.
